Absorbing Boundary Conditions for Wave Problems:
A Review of current Practices and future Perspectives
Abstract
Wave propagation problems posed in large or infinite physical domains must
be truncated (for practical reasons).
New boundary conditions must be imposed on the boundary of the truncated
domain, and must be as transparent, or
absorbing, as possible to prevent outgoing waves from being reflected and
contaminate the solution within the
truncated domain.
In this talk we review past and current techniques used to obtain
appropriate absorbing boundary conditions (ABCs), as
well as their effectiveness on a model problem. We also discuss
preliminary investigations into new directions
to further improve the effectiveness of current ABCs. This is joint work
with Prof. Z. Jackiewicz (Math, ASU)
